If you look at the burners in the furnace..the flame sensor mounted in front of the furthest left burner on the bottom of the burner box...

Tom :

It will have a single insulated wire attached....usually one screw to remove it then clean the probe with some fine sand paper or steel wool. The alternating lights are a pretty good indication that the control board is not getting a good flame signal.

Tom :

Would you like me to link you to a manual for your furnace?

JACUSTOMER-dl2cklck- :

No, I have the manual in front of me. I am reviewing it now

Tom :

Page 15 shows the flame sensor.

JACUSTOMER-dl2cklck- :

Please send the manual

JACUSTOMER-dl2cklck- :

Would it be a green insulated wire on the front connected with a hex screw?

If you look at your meter...there should be a regulator like the one in the pic...see arrow..

Tom :

The vent is the round part pointing down with a screen in it...it has to be open

Tom :

Ok...no problem..

JACUSTOMER-dl2cklck- :

Wow...thought that was it. Regulator was buried by snow. I cleared it out, restarted the unit and it sounded real good. Flame was stronger, but didn't last. Blower came on twice, but flame sputtered out after 50 secs or so.

Tom :

Did you make sure the screen was open?

JACUSTOMER-dl2cklck- :

let me check again...I'm sure that's it...stand-by

Tom :

no problem

JACUSTOMER-dl2cklck- :

Well, we think that was it! Best $23 we've spent in a long time. Thanks Tom. Please remind any other emailers from MN to check the regulator as we have had record snow in the last 24 hours!! Thanks again.
